Star Wars writer Lawrence Kasdan has said he wants to "start fresh" with the franchise's spin-off film.

Kasdan, who wrote The Empire Strikes Back and The Return Of The Jedi, is on board to pen a new Star Wars standalone film, separate from the new trilogy which begins with the JJ Abrams directed Star Wars: Episode VII.

Speaking about the project, which he is remaining tight-lipped about regarding the characters involved and the plot, Kasdan revealed that he will be working on the film with X-Men: Days of Future Past screenwriter Simon Kinberg.

He told the LA Times: "I'm trying to start fresh. There are certain pleasures that we think the saga can bring to people that they've been missing, and we're hoping to bring them that, and at the same time, have them feel that it's all new.

"The ones I worked on were a long time ago, and they had a slightly different feeling than the ones that followed. The first three, Star Wars, Empire and Return of the Jedi, are all sort of more about people than the ones that followed."

According to reports, Disney plan the spin-off films to include vehicles for Han Solo and Boba Fett. Solo's film would be set in the time period between Revenge Of The Sith and A New Hope, while the Boba Fett film would take place either between A New Hope and The Empire Strikes Back, or between The Empire Strikes Back and Return Of The Jedi.
